用声音实时监测土壤湿度，让设备自己发声预警缺水。
On-device Internet of Sounds Sonification with Wavetable Synthesis Techniques for Soil Moisture Monitoring in Water Scarcity Contexts
- 在设备端用波表合成技术将土壤数据转为声音
- 实现本地化实时声化，无需上传数据
- 适合缺水地区野外监测，适合听觉感知需求者
声化是将数据映射为声音以传达原始数据信息的策略，正成为互联网声音（IoS）网络中复杂数据流声学表达与传播的可行方案。本文提出一种面向全球水资源日益紧缺背景下的土壤湿度监测场景的IoS声化实现方法。以往研究多聚焦于IoS网络应用与服务层面的声化，而本文探索基于波表合成技术的设备级声化，将传感器数据映射至声学参数。论文形式化了一种设备端波表声化方法，并展示其原型实现，最后将其置于土壤湿度监测任务中进行评估与分析。
原文摘要 · Abstract (English)
Sonification, the mapping of data to sound to communicate information about the original data source, is becoming a viable strategy for the sonic representation and communication of information derived from the complex flows of data exchanged across Internet of Sounds (IoS) networks. This paper presents an IoS sonification implementation for monitoring soil moisture levels within the broader context of the globally increasing water scarcity. While previous work has focused on sonifications operating on the applications and services level of the IoS network infrastructure, this paper explores device-level sonification using wavetable synthesis techniques to map sensor data to acoustic parameters. An approach to on-device wavetable sonification is formalized, and a prototype implementation is presented and explored before the approach is contextualised with regard to the soil moisture monitoring tasks.
